DEMO'UNTABLE TIRE RIM.

Application filed October 3, 1925. Serial No. 60,300.

The invention relates to means for mountmg pneumatic and other tires on automobile and other vehicle wheels, and has for its object the provision of a rim made in two mating annular sections, and providing each section with integral flanges extending in wardly of the section in each instance and curved baclrwardly of the section, and provi ing cl'ianneled clamping members to ensaid flanges having their edges turned inwardly to engage under the backwardly curved portions or t 1e flanges, a cotter pin or other suitable member being inserted through an opening in each of the flanges and a groove in the clamping member to prevent accidental displacement of the clamping member.

The invention will be described in detail 'weinattter and illustrated in the accomiianying drawings in which .L igure 1 is a side view in elevation of a eel showing the improved rim in position l igure a transverse sectional view on a plane indicated by the line 2-2 of Figure 1, i ure 3 is plan view of one of the lag members, and ure is a traginental, view of the inner side oi? the rim showing the flanges.

in the drawings similar reference characters will be u l to designate corresponding parts throin. out the several v.iews.

In ll" 'ure 1 a eel A. is shown on which improved demountable rim 1 is in posihold by clamping members 13 of the cat-ing the pneumatic tire he rim 1 is made. up sections shown clearly in -.d sections being designated 2 each of said annular sections is idcg with flanges t extending inward .t' the rim and curved away from one anfrom the meeting edges of the hown at 5, and thus forming reween the outer curved portions o inner suriafe of the section. The clampins' member comprises a plate 7 havr edges tori-nod with upwardly curved and the edges of said flanges 8 curved toward one another as shown at 9 to engage in the recesses 6. The flanges 4: are provided with mating openings 10, and the clamping member 7 has oppositely disposed grooves 11 in the inwardly curved portion 9 that alines with the openings 10 in the flanges when the clamping member is in position to receive the cotter pin 12 or other suitable member to hold the clamping member in engagement with the flanges and thus lock the two sections 2 and 3 of the rim 1 together.

The telly D of the wheel A is provided with recesses 18 to receive the clamping members 7 when the rim and tire are mounted on the wheel. E indicates the usual telly band provided with a flange F to engage one side of the rim 1, the other side of the rim 1 being held in engagement with the wheel by means of the clamping members B heretofore described.

It will be apparent that when the device is assembled and placed on the wheel, as shown in Figures 1 and 2, the rim will be held eflectually assembled by the clamping members engaging flanges 4iand also the flanges 4t and the clamping members will prevent circumferential movement of the rim 1 relatively to the flanged band E and the telly D.

What is claimed is 1. Means for clamping the two annular sections of a demountable rim, comprising mating flanges on the sections and extending inwardly thereof, said flanges having aligned openings therein, clamping members adapted to engage said mating flanges and provided with grooves to aline with said openings, and pins insertible through said openings and engaging said grooves to lock the clamping members on said flanges.

2. A demountable rim comprising two mating annular sections provided with mating, integral, backwardly curved flanges at intervals around them and interiorly thereof, clamping members adapted to engage said flanges, each of said clamping members including a plate having inwardly curved edges to engage within the backwardly curved flanges, said flanges having openings therein adapted to aline and the edges of the clamping members provided with grooves to aline with said openings, and pins insertable through said openings and engaging said grooves to lock the clamping members on said flanges.

In testimony whereof I aflix my signature.

HAROLD W. OLSEN.
